Bilateral disk swelling and marked peripapillary and macular exudates
were found on routine ophthalmologic examination in a 12 1/2-year-old
girl. Eleven months later, with persistent findings, her blood pressur
e was found to be extremely elevated. She had an Ask-Upmark kidney, a
rare form of segmental renal hypoplasia. The Ask-Upmark kidney abnorma
lity occurs primarily in young women and is associated with hypertensi
on. The disk edema and retinopathy resolved after the hypertension was
controlled. Hypertensive retinopathy can sometimes resemble neuroreti
nitis. (C) 1997 by Elsevier Science Inc. All rights reserved.
